This statement is true because the poet Hood prophesied that
Can also speak. The reflection of the movement of sound on a flat surface was to be recorded with the tip of a needle
Edison decided. He decided to carry out the plan with the help of a German craftsman named Kuezi. He was going to be working day and night like Edison. The key, as Edison suggested, was to make the device so that it had two poles on a wooden plank. They had a long horizontal screw attached to them. A handle was planned to rotate one end of this screw. This long skewer was fitted with a brass cylinder and two small pipes were connected on either side. Stretch a curtain on each of these tubes
The plan was to fit two needle tips in the middle. Working thirty hours a day, the quiz put all its skills to the test, and Edison, the well-known nursery rhyme "Mary Hand a Little Lamb," began spinning the handle of the machine with one hand. As soon as the song was over, he pulled back the needle. Turn the screw upside down and turn the cylinder back to where it was before starting the song.
Then the second pipe with the curtain and the blunt pin on that pipe fitted to the first cylinder. Now he turned the handle again, and to his surprise, his words, 'Merry hand a little lamb', could be clearly heard from the nursery rhyme. Thus the first test of the phonograph was successful. The very next day
Edison visits Scientific American's office
News of this spread throughout the New York newspaper.
At 11 o'clock that same night, Edison took the device to the President of the United States, Shri. Entered the Hague. He and his wife were amazed when he showed them how to operate the device, and they greeted Edison.
The demonstration of the phonograph lasted until three in the morning. After the first model was made in 1877, he made many improvements. In those days, in order to type the letters, the manager gave a speech on the plate himself, went to the plate clerk and listened to the typing.
→ The most important discovery - the light bulb and the distribution of electricity.
This is an amazing step in the 19th century and an important step for the welfare of human beings. The most important discovery that revolutionized human life by changing the way of life of the whole world is the light bulb.
Friends, he applied for a patent for an electric lamp that illuminated the whole world on October 21, 1879. He received a patent in January 1880. The invention of the electric lamp is very interesting. His wealthy friend for this research
Yonor Laurie promised to provide as much material as needed. All research 'Edison Electric
The company was started by this company. Even today, General Electric is one of the largest companies in the world
One is working. Before making this electric day, Edison met Professor Walker of Phil Philadelphia Devil Visakhapatnam. Edison was the first to discover the parallel connection that still exists today. So he realized that even if one lamp was turned on, the other lights would not go out.
He first took a thin wire from the platinum side and released a large stream of electricity into it. It glowed a little and burned. He spent several days in this experiment. He wanted a substance that would heat up red and give light. Also, it will last a long time without burning. In almost thirteen months of research, he experimented with many substances. The feature is that
He was not disappointed at all. He was so stubborn that his every experiment was his
There was a smile on his face.
He made a wire from the front of the coal. Of course, hundreds of substances used to star before. He fitted the carbon wire into a vacuum glass tube by means of a self-made vacuum pump to make a vacuum cavity. When Edison released an electric current from that carbon wire, a very beautiful and glowing light was produced in the glass tube; But even this wire did not last long.
The workers continued to make carbon wire for two full days and two nights. He finally got the carbon
He connected the wire and the copper wire and re-inserted the wire into the glass tube and emptied the tube.
Then when he released electricity into the vacuum tube. But then a quiet and glowing electric light
Began to shine in the tube. It was the first light bulb ever seen by Edison. This was followed by carbonation of fibers of many materials such as grass, sticks, knapsacks, paper, card boards. In the end, the filament made of bamboo wire, however, lasted a long time.
Seeing this, Edison began to study the bamboo branch and bowed down. For the Menlo Park Eagle experiment, he collected nearly 6,000 samples of bamboo from the Malay Peninsula, Burma, and South China. Samples of 6,000 electric lamps were made from it, and finally three of its bamboos and one kind of cane were chosen for the star of the lamp which belonged to her on the banks of the Amazon River.
In 1880, he received an application in October 1879. Approved in this way, he hung several lamps on his tree in the designated park and allowed all the people to see, keeping all these lamps open for the day literally. Millions of people saw this wonder. That is why it is said,
Should. ' As soon as he made these electric lamps, the idea came to his head that for electric light
A factory should be set up to make the necessary materials like buttons, caps, lamps. As
He set up a central power plant at a strategic location in the center
According to the plan to supply electricity to the city by laying wires all over the city, 'The New York Edison Illuminating Company' was formed. H. Potter reached out to the engine manufacturer and built the engine. Dynamics have already been created. At that time, according to the plan, he first built an engine of 105 horsepower and 350 fans per minute, and on Saturday, September 4, 1882, the whole of New York City was electrified. Meanwhile, he also invented the electric fuse.
Columbia
Electric lights were switched on in public places like Naigriha and later in the house as well. The period from 1880 to 1890 is the period of Edison's career as he made 300 connections and obtained 300 patents. इ.स. At the International Exhibition at Kolandia in 1893, the flash of his electric lamp was spectacular.
The reason for the fight was that hundreds of people came from all over the United States and Europe to see the exhibition. The main hall of the exhibition, which would attract everyone, was lined with electric lanterns. In the spacious courtyard of the exhibition, on the magnificent arches, on the pillars, on the trees, thousands of star-studded lanterns were lit by Edison, besides the large letters 'Columbia International Exhibition'
From the glow of electric light of changing colors on the water fountain in the fountain he had created
His creativity was manifesting. That is why he was felicitated on September 12, 1922. The exhibition introduced Edison's current to the world. Aedes adds invaluable value to human well-being. In 1890 he turned his attention to iron production; But that industry did not succeed; But he did not hesitate to set up a cement factory. Other devices that run on electricity include dustless trains, electric pens, and so on
He raised.
